Q:
# Which situation is best modeled with a division expression?a-finding the number of equal-sized parts into which a number can be splitb-finding the combined value of several different numbersc-finding the distance between two numbers on a number lined-finding the total value when several of the same number are grouped togetherAND Joylin’s work to solve a math problem is shown below.Problem: Manny walked 5/16 of the distance to the library in 1/3 of an hour. If he walks at a constant rate, what is the total amount of time he will spend walking to the library?What was Joylin’s first error?a-She switched the divisor and the dividend when creating an equation to model the problem in step 1.b-She replaced both the divisor and the dividend with their reciprocals when changing division to multiplication in step 2.c-She multiplied the two numerators and the two denominators to generate her product in step 3.d-She reduced the improper fraction incorrectly when getting her final answer.

Accepted Solution

A:

joylins first error is option a.finding the number of equal-sized parts into which a number can be splitStep-by-step explanation:Let us split the number 80 into 10 equal parts.80 = 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8= 8 + 8 + 8 +...to 10 times= 8(10)or So, if N is any number and p is one of its equal part, then the number of parts into which N is split by p is .Hence, finding the number of equal-sized parts is best modeled with a division expression.i think manny question is incomplete.please mark it as brainliest.i have tried very hard.hope this helps
